Y= -5x -4 because you would do slope intercept form and sub the y and x in for -4 and 0
When solving a system by graphing you need to see where the lines intersect.
Below is a picture of these lines graphed. The green line is y = x +4 and the blue line is y = 4x - 1
The red dot represents the intersection is about (1, 5)
The original point is: (1.667, 5.667)

Answer:

And the best option would be:

Step-by-step explanation:
We assume that the distribution for the random variable is:

For this case we want to calculate the following probability:

And we can use the normal standard distribution or excel and we got:

And the best option would be:

Answer:
The correct answer is C. 1/10.
Step-by-step explanation:
Given that a spinner has 10 equal sections numbered 1 through 10, to determine what is the probability of landing on the 6, the following calculation must be performed:
6 = 1 side only
10 = 10 options
1/10 = X
Therefore, the probability of the spinner landing on the 6 is 1/10.
